SpaceX’s Starhopper gains thruster pods as hop test preparations ramp up
Amid a flurry of new construction at SpaceX’s Boca Chica facilities, technicians have begun to install thruster pods on Starhopper in anticipation of the prototype’s first untethered flights.
According to CEO Elon Musk, Starhopper’s “untethered hover tests” will begin with just one Raptor engine installed, potentially allowing hops to restart within the next few weeks. SpaceX is currently testing Raptor SN03 (and possibly SN02) a few hundred miles north in McGregor, Texas, just a few hours’ drive south once the engine is deemed flight-ready. Meanwhile, Starhopper itself needs a considerable amount of new hardware before it can begin Raptor-powered flight testing.
A Falcon Raptor-powered Starship
Purely from a visible perspective, the most important component Starhopper is missing is a way to control its attitude and remain stable while under Raptor power, particularly critical for hovering. Enter the aptly-named attitude control system (ACS), essentially a pod of omnidirectional thrusters. SpaceX already happens to have its own extremely mature ACS proven over nearly two dozen successful Falcon 9 and Heavy booster landings, as well as every Falcon upper stage that has ever flown. SpaceX’s ACS is based on powerful nitrogen gas thrusters, known for their white puffs during Falcon 9 booster recovery and landing operations.
On May 6th and 7th, SpaceX began to install what looked like Falcon ACS pods on Starhopper. Curiously, of the two pairs of thrusters now installed, half appear to be taken directly off of older mothballed Falcon 9 boosters, while the other two seem to have been acquired from a Falcon 9 Block 5 rocket. The latter pods may very well have come from Falcon 9 B1050, the booster that unintentionally landed in the Atlantic Ocean last December.
Based on the asymmetric location of the first two pod groups, Starhopper’s ACS will probably use a tripod layout. Additionally, the reason for the thruster pairs – versus Falcon 9’s single pods – is likely simple: Starhopper is far heavier than a Falcon booster. To get the same level of control authority, SpaceX is thus pairing pods together to double the functional strength of Starhopper’s ACS.
This leads smoothly to the installation of two (likely soon to be three) new composite-overwrapped pressure vessels (COPVs). Starhopper already has two COPVs installed on the outside of its upper tank dome, now effectively confirmed to be helium containers needed to pressurize the vehicle’s methane and oxygen tanks. Based on the fact that Starhopper’s new ACS pods appear to have come straight from Falcon boosters, it’s safe to say that the 2 (or 3) new COPVs will supply the hopper’s thrusters with gaseous nitrogen.
The Ugly Starshipling
In general, this is just the latest chapter in the book of the oddity that is Starhopper. With helium tank pressurization and nitrogen ACS thrusters taken straight from Falcon 9, a major facet of SpaceX’s Mars architecture is entirely missing from the prototype. Known as autogenous pressurization, BFR was meant to use gasified versions of its onboard liquid oxygen and methane to pressurize its propellant tanks. In a similar vein, BFR was expected to integrated the same propellant into its ACS. Simply put, helium is simply out of the question if SpaceX wants to realize its reusable Mars transport architecture. Mars does have a minute quantity of nitrogen available in its already very thin atmosphere, but extracting hundreds or thousands of kilograms is impractical in the near-term, particularly if the first Starship have to carry all of their extraction equipment from Earth.
Although Musk has seemingly confirmed that Starship and Super Heavy will use ACS thrusters more akin to the Falcon family’s cold nitrogen gas pods, he did also confirm that autogenous pressurization would be a part of even the earliest iterations of the rocket. The move from carbon fiber to steel tanks likely made a major difference, as carbon composites have extremely limited heat resistance.
Without autogenous pressurization and propellant tanks closer to the thickness of orbit-capable Starships, Starhopper is really more of a mobile test stand for Raptor than anything else. The ungainly vehicle also offers SpaceX engineers an opportunity to test Starship/Super Heavy avionics in flight conditions, particularly with respect to controlling a real Raptor engine on the fly.

Elon Musk shed two new bits of detail on Starship following its 13th test launch, which was an overwhelming success.
SpaceX launched Starship for the 13th time last Friday after two delays: one on Monday when several Raptor engines did not ignite, and another on Thursday due to unfavorable weather conditions in Starbase, Texas.
The launch was overwhelmingly successful. SpaceX was able to complete a necessary test of the heat shield tiles by increasing the acceleration of Starship from launch throughout the flight; 20 Starlink v3 satellites were released with no issue; the Super Heavy Booster landed safely in the Gulf of America, Ship successfully reignited engines while in space; and it also splashed down without incident in the Indian Ocean.
SpaceX Starship just nailed something it’s never done before
Nevertheless, more details are coming out about Starship, and Musk is doing the talking.
Starship Will Be Retrieved in the Ocean
Musk revealed on Tuesday night that Starship would be recovered by a ship in the Indian Ocean. SpaceX routinely tries to recover Starship after splashdown in an effort to find out more about the flight by examining the spacecraft afterward.

This helps engineers find out more about why things might have happened, allows them to examine any potential damage or anomalies that might have occurred, and increases the chances of an even more successful flight next time thanks to the additional information recovered.
Ship Could Have Been Caught by Tower Arms, Musk claims
Musk has already indicated that SpaceX will plan to attempt a catch of Starship with the 14th test flight. While this would be a major accomplishment, it would be an expected next step, considering the fact that the Super Heavy Booster has already been caught by the chopsticks on numerous occasions.

A ship catch would be a great indication of where SpaceX stands in terms of reusability and launch cadence. A successful catch with relatively no incidents would be a good sign that SpaceX is nearing a more frequent launch of Starship, but also that the reusability of the massive rocket would be something many would expect in the near future.
It is a necessity to make life multiplanetary.
Elon Musk has updated his timeline for when humans will walk on Mars and for when ships will simply get there.
The objective of getting to Mars has been one of Musk’s biggest goals since becoming a serial entrepreneur and realizing that time on Earth is limited. Musk has said several times he hopes to die on Mars, and not by impact.
Musk now believes that people will be on Mars in “roughly 5 to 7 years.” He said that a Mars lander will get there “a few years sooner.”

The response from Musk comes after NASA Administrator Jared Isaacman said that SpaceX’s biggest priority is the Moon and not Mars. Because of this, Isaacman conceded that he believes nuclear power and propulsion investments will provide “potentially the pathway with the fewest miracles required to put four people on Mars in the next 10 to 15 years.”
Of course, this is what NASA can do through taxpayer funding and nuclear investments, he added.
Musk’s grand ambitions are much more optimistic than most, and it is certainly a double-edged sword. This is not the first time timelines for Mars have been somewhat lofty, especially to those normal thinkers like you and me, not super geniuses like Musk.
In fact, the SpaceX and Tesla frontman has said on at least a dozen occasions that we could be on Mars in the coming years. Musk said 2020 would be the big year as early as 2009. In 2020, he was “highly confident” of a landing in 2026, and had even said 2024 in a best-case scenario.
The point is, the range has varied, and it’s anyone’s guess when we’ll get there. This latest adjustment to the timeline is typical of Musk, and while the Moon has seemingly taken priority over Mars, it is still worth mentioning that the ultimate goal is to make life multiplanetary, and it starts potentially with the Red Planet.
SpaceX (NASDAQ: SPCX) got an absolutely crazy price target rating from Raymond James after the company experienced a tough first few weeks following its Initial Public Offering (IPO).
Despite the tumultuous start, SpaceX has plenty of believers, and the company’s massively successful Starship launch last Friday, its 13th test flight of the massive rocket, went so smoothly that Raymond James analysts pushed its price target on the company to roughly 7 times its current trading level.
SpaceX Starship just nailed something it’s never done before
The firm officially put a “Strong Buy” rating and an $800 price target on the stock. It currently trades at around $113. Its all-time high is $225.64, reaching this trading level shortly after shares first went public.
Raymond James’ price target is tied to the firm’s confidence after Starship’s 13th test flight. Analysts at the firm said it was an incremental step that reduces engineering risks, citing the widely successful heat shield test that CEO Elon Musk recently detailed, the smooth deployment of Starlink V3 satellites, and a successful in-space engine relight.
SpaceX also managed to see Starship splash down safely in the Indian Ocean, while the Super Heavy Booster fell down to the Gulf of America with no incidents.
It is interesting to see these launches have such a tremendous impact on the stock and what investors think of it. After SpaceX initially delayed the Starship launch last week, shares fell tremendously. Most probably did not realize that the stand-down is a standard practice, especially if everything is not perfect.
The mission was initially aborted due to an issue with Raptor engines. This was resolved, and Starship launched last Friday after another delay on Thursday, which was caused by weather.
Now that analysts have seen what SpaceX launches are capable of and how impressive the feat is, firms are adjusting their price targets accordingly, making it known that they have high expectations for the space exploration company.
